Product details
Overview
DF36087FPV from Renesas Electronics is a 16-bit single-chip microcomputer in the H8/36087 Group, featuring the H8/300H CPU core with instruction set compatibility to H8/300. It integrates on-chip ROM (128 KB), RAM (8 KB), 3-channel SCI, 2-channel I2C, 16-bit timer/counters, and operates at up to 20 MHz in active mode. It targets embedded control in industrial instrumentation and motor drive interfaces.
For engineers reviewing the DF36087FPV datasheet, DF36087FPV pinout, DF36087FPV application, or DF36087FPV equivalent, this page delivers verified package mapping (LQFP-100), confirmed pin functions per Renesas Hardware Manual Rev.2.00, real-time interrupt handling latency (≤1.5 µs), and validated alternatives for legacy H8-based system continuity planning.
Technical Context
The DF36087FPV implements the H8/300H CPU with 24-bit address space, supporting both little-endian and big-endian data access via software configuration. Its memory map includes dedicated areas for on-chip ROM (0x000000–0x1FFFF), RAM (0xFFE000–0xFFFFFF), and peripheral registers (0xF00000–0xF00FFF).
Power management is handled by four low-power modes-Sleep, Standby, Subsleep, and Subactive-with independent module standby control via MSTCR1/MSTCR2 registers. Clock generation supports crystal (1–20 MHz), ceramic resonator, or external clock input, plus a separate 32.768 kHz subclock for RTC functionality.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F366ACDFP | Successor H8S/2600 series part with enhanced 32-bit addressing, larger RAM (16 KB), and USB 2.0 interface; not pin-compatible. | Required for new designs needing USB connectivity or >128 KB code space; unsuitable for drop-in replacement due to different pinout and register layout. | Select only when migrating legacy H8 firmware to modern toolchain and expanding peripheral requirements beyond DF36087FPV capabilities. |
| HD64F36087F | Same silicon die and functional spec; differs only in marking and packaging (plastic DIP vs. LQFP); identical electrical behavior and timing. | Used in through-hole prototyping or legacy repair; shares same ROM/RAM map, interrupt vectors, and peripheral register set. | Valid for board-level substitution where mechanical fit permits; no firmware or schematic changes required. |
Compared with DF36087FPV, R5F366ACDFP offers architectural scalability but demands full redesign, while HD64F36087F provides mechanical interchangeability with zero firmware impact-making it the only true form-fit-function alternative.

FAQ
What is the maximum operating frequency of the DF36087FPV?
The DF36087FPV operates at a maximum frequency of 20 MHz in Active mode when supplied with a stable 3.0–5.5 V VCC and driven by an external crystal or clock source within specification. This frequency determines instruction cycle timing and peripheral clock derivation-critical for meeting real-time deadlines in motor control loops or communication protocols. The DF36087FPV maintains full functionality and timing compliance up to this rated speed under all specified temperature and voltage conditions.
Does the DF36087FPV support in-system programming (ISP)?
Yes, the DF36087FPV supports in-system programming via its on-chip Flash ROM. Firmware updates can be performed through the SCI or I²C interface using Renesas-provided bootloader routines, eliminating the need for external programmers. This capability is essential for field upgrades and remote maintenance of deployed systems. The DF36087FPV's flash architecture allows sector erase and byte-write operations, enabling robust and flexible firmware management without hardware intervention.
What are the power management modes supported by the DF36087FPV?
The DF36087FPV supports four distinct low-power modes: Sleep, Standby, Subsleep, and Subactive. Each mode disables specific clock domains and peripheral blocks to reduce current draw-from ~1.2 mA in Standby down to ≤10 µA in Subsleep. Mode transitions are controlled via SYSCR1/SYSCR2 registers and triggered by software or external events. These modes are integral to extending battery life in portable instrumentation and enabling rapid wake-up (<10 µs) for event-driven sensing applications using the DF36087FPV.
Is the DF36087FPV pin-compatible with other H8/36087-series variants?
No, the DF36087FPV is not universally pin-compatible across all H8/36087-series variants. While it shares the LQFP-100 package with some members (e.g., DF36087F), differences in pin function allocation exist-for example, P85–P87 are reserved for E7/E8 emulator use and unavailable for general I/O in debug configurations. The DF36087FPV's pinout is defined in Section 1.3 of the Renesas H8/36087 Group Hardware Manual Rev.2.00 and must be verified against target variant datasheets before substitution.
What is the role of the NMI pin on the DF36087FPV?
The NMI (Non-Maskable Interrupt) pin on the DF36087FPV serves as a dedicated, high-priority interrupt input for critical system events such as power failure, thermal shutdown, or hardware fault detection. Unlike maskable interrupts, NMI cannot be disabled by software and triggers immediate vector fetch from fixed address 0x000010. During on-chip emulator debugging (E7/E8), this pin is reserved and repurposed-so the DF36087FPV's NMI functionality must be validated in final production configuration, not debug setup.
